Letters Patent No. 96,904, dated November 16, 1869.

IMPROVEMENT IN CARRIAGE-THILL COUPLINGS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, CYRUS FISHER, of Canton, in the county of Norfolk, and State of Massachusetts, have invented a new and useful Improvement in Thin- Couplings; and I do hereby declare that the following is a full, clear, and exact description of the construc tion and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side elevation, and

Figure 2, a front elevation.

This invention has for its object the fastening of the thills of acarriage to its forward axl'e,.so that they can be readily and easily detached, when desired; and

It consists in a strap-bolt, attached-to the rear end of each of the thills, and fitting in a hole in a trunnioued block, which is confined between clips on the axle, the said strap-bolt having a screw-threaded end, by means of which and a nut, casual detachment of the thills is prevented.

In the drawings A ISIJI16 thili, having a rear downwardly-curved end, on which is secured a bolt, a, by means of straps a, cast solid with the bolt, and screwed to the thill.

B B are the clips, placed on the axle D, and supporting the horizontal rocker-shaft or truunioued block b, which is provided with conicaheuded trunnions, and throughwhich is made a perpendicular hole, for the reception of the strap-bolt a, which, after occupying the orifice in the trunnioned block, is fastened in place by simply screwing a nut, a", upon its lower threaded end.

On unscrewing the nut, the thill may be readily removed.

Thus the thill is attached. and removed without disturbing any of the other parts of the coupling-ammratus.

Having thus described my invention,

\Vhat I claim as' new, and desire to secure by Let-.

ters Patent, is--' g The combination and arrangement of the separate clips B B, trunuioned block I), having conical-ended trunnion, and strap-bolt a, all constructed and operating in the manner and or the purpose specified.

CYRUS FISHER.
